Pruning is very important in dragon fruit cultivation. Besides, it provides good framework and balance for plant canopy, it allows good ventilation for plants. Small insects might live within the compact canopy making spraying of insects difficult. I have observed that farmers practise the wrong way to prune dragon fruits making it attack by insects badly.
The top pic shows how farmers pruned dragon fruits the wrong way.It has become multi layer that caused heavy load to the support stand.
Below is the correct way how to prune dragon fruit. The top part should be free from new shoot growth allowing sunshine to penetrate and good ventilation.

I had observed how the farmers made their own organic fertilizers and the farm was very clean. I traced out some secrets of how they control diseases using the cheapest way. The only disease I noticed was brown rust spot caused by Dothirella but it is under control.The weather was wet and dry. Brunei had a very good potential to produce dragon fruits however early works should be done such as suitable land establishment, good and reliable planting materials, management practices and marketing as well downstream activities must be well planed and worked out. The people are eager to plant if the incentives are right.
Prior going to Brunei, I was asked to go to investigate disease breakout in Johore. About 50 acres were infected. What I observed that due to flooding, but the farmers did not control the disease from spreading partly due to bad sanitation and field agronomic activities.Apart from that farmers did not practice the correct pruning techniques, the canopy was dense and crowded that harvest a lot of insects and fungus.One more thing they did not pruned at the joints, making easy infection of diseases to enter if the branches were half-pruned.

This dragon fruit farm was located on a former oil palm plantation situated in Malacca. It was clean and fruiting well. One of the problems I managed to counter was that the fruits were attacked by fruit flies- no incidence have ever reported some where else. So the best way to control is hand-wrapped all the fruits at early stage of fruiting.

The local name for dragon fruit is ‘buah naga’ or ‘buah mata naga’. In
Since dragon fruits originated from different climatic conditions, it has to undergo environmental adaptations and agromanagement practices.
If R & D is been prioritize, then one day it will become one of the leading export earner of Malaysia. The pic above shows one of the dragon fruit plantation in Malaysia .This farm is araound 100 acres. There many such farms in the country.

There are many techniques of how dragon fruits can be planted. It can be planted in row, single and so forth. Not only dragon fruits can be planting as big plantations but it could planted in a house compound. Both big and small growers can benefit from this crop- as only planting techniques needs some changes. Be creative

The normal or conventional planting density in dragon fruits is 2 meter X 3 meter (6 ft.X 9 ft.).This means that for an acre only 2,000 plants could be planted.It is a good idea if the planting density could be increased so that many plants could be plant per unit area.
I have seen close planting of dragon fruits in Chiangmai. However, during my visit it was not fruiting season. I think their planting density is 1 ft X 10 ft.

In the pic above, dragon fruit outshines guava,mangosteen, 'buah tampoi' and rambutan.These fruits make a beautiful basket of fruits.

Yellow dragon fruits are one the varieties planted here.However, only it is planted in a small scale.I have tasted and it is very sweet but the seeds are larger than the white and red varieties. The skin colour looks yellow and the fruits are quite small between 150 to 250 g compared to the red varieties which easily weighs up to 600-800g.

Report says that Betanin, or Beetroot Red, is a red glycosidic food dye obtained from beetroot; its glycone, obtained by hydrolyzing away the glucose molecule, is betanidin. As a food additive, its E number is E162. Betanin degrades when subjected to light, heat, and oxygen; therefore, it is used in frozen products, products with short shelf life, or products sold in dry state. 
Betanin can survive pasteurization when in products with high sugar content. Its sensitivity to oxygen is highest in products with high content of water and/or containing metal cations (eg. iron and copper); antioxidants like ascorbic acid and sequestrants can slow this process down, together with suitable packaging. In dry form betanin is stable in presence of oxygen.
Betanin is usually obtained from the extract of beet juice; the concentration of betanin in red beet can reach 300-600 mg/kg. Other dietary sources of betanin and other betalains include the opuntia cactus, Swiss chard, and the leaves of some strains of amaranth.
While , lycopene is a red, fat-soluble pigment found in vegetables, and most commonly found in tomatoes. It is one of a family of pigments called carotenoids. Carotenoids are naturally occurring pigments responsible for the brightly colored fall leaves and the vivid colors of flowers, fruits, and vegetables. In fruits and vegetables, these pigments range in hue from bright yellow in squash, to orange in carrots, to bright red in tomatoes and peppers.
Lycopene is the only micronutrient whose serum level was shown to be inversely related to the risk of age-related macular degeneration.

Dragon fruits are easy to grow however it needs support or stake to stand on. Its succulent stems are tender and branches upwards and later downwards. Long and mature branches also needs support to rest on before flowering commences. The soil must be good condition such as sand soil and sand loam soil because their have rich an organic material for growing
Besides being consumed fresh, the red dragon fruit can be processed into cordial, jam,wine and other products. There are reports that the content and the skin of dragon fruit can become natural food coloring and lipsticks. This natural food coloring is safe to be used because it does not have any side effects and no harm to our health. Young shoots can be cooked just like we cook lady's finger. Its nutritious. There is another source vegetable which had medicinal value in our diet. The dry flowers can be processed to make tea.
The potential of the dragon fruit plantation to increase is very bright due to untapped downstream activities of its by products. This is supported by early investment return, less risk high market demand compared other tropical fruits.
